In this post I wanted to highlight percona.com/bugs/<tool> , for example: percona.com/bugs/pt-stalk. This only works for Percona Toolkit. We often advise people to check a tool’s current bugs, but we don’t always say how.
The official link for Percona Toolkit bugs on Launchpad is https://bugs.launchpad.net/percona-toolkit/+bugs, but then you still have search from there. So this quick link is a lot easier if, for example, pt-stalk fails to parse df with NFS and you wonder if that’s a known bug (yes it is). Please never hesitate to file bugs. We’re always eager to improve our software.
